The cause of the wreck of the ship Edmund Fitzgerald in a severe storm on Lake Superior is still unknown. When the sunken wreckage of the vessel was found, searchers discovered the hull in two pieces lying close together. The storm's violent waves would have caused separate pieces floating even briefly on the surface to drift apart. Therefore, the breakup of the hull can be ruled out as the cause of the sinking.
Which of the following is an assumption on which the argument depends?
Ships as large as the Edmund Fitzgerald rarely sink except in the most violent weather.
Underwater currents at the time of the storm did not move the separated pieces of the hull together again.
Pieces of the hull would have sunk more quickly than the intact hull would have.
The waves of the storm were not violent enough to have caused the ship to break up on the surface.
If the ship broke up before sinking, the pieces of the hull would not have remained on the surface for very long.
①船体残骸两半离得很近
②如果船体是分开的话，storm会使得两半drift apart
结论：船体分开不是导致船在storm中沉没的原因
这个题就是很典型的自己想完全想不出...但是看选项就可以大彻大悟型的
storm的wave会使pieces分开，但是underwater current会不会有可能使得这个pieces连在一起
